What the Alert is Detecting
(Default)
A travel sensor failure or large
travel deviation has resulted in
fallback to pressure control.
The supply pressure has
exceeded the Supply Pressure
Hi Alert Point.
The supply pressure is lower
than the Supply Pressure Lo
Alert Point.
The temperature is greater
than the Temperature Hi Alert
Point.
The temperature is lower than
the Temperature Lo Alert
Point.
Effect on Valve/Instrument
None - Indicates a reduced
performance condition.
None - Indicates a condition
that could cause damage to
the instrument or actuator.
None - Indicates a condition
that could reduce performance
or prevent the valve from
shutting tightly.
None - Indicates a condition
that could shorten service life
or lead to reduced
